Greetings.

I have a 16 x 8 matrix that, in turn, contains lists in some of its coordinates. I know how to send the matrix to a text file, but I can not take the data from the file and rewrite it in a new matrix as integers, respecting the internal lists.

This is an example of the matrix

That's the matrix in the text file. Now I want to return it to an array in Python. I have seen that some use numpy, but since I am using python 3.5.2, I do not load the library. I would like to know if you can give me another method to achieve my goal. In advance, thank you very much to anyone who can help me.

python python-3.x

You can do assi, using json :

import json
matx = [1,2,3,4,5, [1,2,3, [1,2]]]

To send the matrix to a text file:

with open('tests.txt', 'w') as f:
    json.dump(matx, f)

To take the data from the file:

with open('tests.txt', 'r') as f:
    matx = json.load(f)

print(matx) # [1, 2, 3, 4, 5, [1, 2, 3, [1, 2]]]
